Hydraulic fitting types

Types of hydraulic fittings vary depending on their sizes, configuration, and thread types. The three most common types of hose fittings are O-ring, mated angle and threaded.

How do I know what type of hydraulic fittings I have?

There are six types of threads commonly used on hydraulic tube fittings: UN/UNF. NPT/NPTF. BSPP (BSP, Parallel) ... Four Steps to Thread Identification

Step 1 – Determine if the thread is tapered or parallel.
Step 2 – Determine the pitch. ...
Step 3 – Determine the size. ...
Step 4 – Designate the thread.

What does JIC mean in hydraulic fittings?

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.

What is the difference between JIC and JIS?

Usage difference: JIS hydraulic fttings mainly used in Japanese and Korean heavy equipment such as Komatsu, Kobelco, Hitachi, Kubota etc, often used as hose adaptors. JIC hydraulic fittings mainly used in North America market, also popular in the worldwides.

What are the most common hydraulic fittings?

The three most common fitting ends and connector types for hydraulic fittings are the O-ring, the mated angle, and the tapered thread connectors. Although these are the most popular choices, several other types are used in different and specialised applications.

What is the difference between JIC and SAE fittings?

JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, and 10 share the same thread size.

How do I know if my hydraulic fittings are JIC?

In a word,if the fittings has a 37° flare (sealing surface angle)and straight United National Fine straight Threads (UNF) after inspection. It can be identified be JIC fitting.

How do you identify an fitting?

First determine if the threads are parallel or tapered tapered threads get smaller toward the

What is SAE fitting?

Society of Automotive Engineers (SAE) Threads These fittings are commonly used in refrigeration, automative and low presure applications. SAE 45° SAE J512. SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve.

Is JIC 37 same as an?

JIC Steps In The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

Is UNF and JIC the same?

JIC / SAE 37 degree / UNF Straight. The only effective difference is that JIC (also known as SAE 37 degree) has a conical seating face (37 degree or 74 degree total angle) and UNF Straight has a flat seat - sealing being effected by use of a washer. Male JIC fittings have a convex cone, female fittings a concave cone.

What does BSP stand for in hydraulic fittings?

British Standard Pipe (BSP) Also referred to as Whitworth threads, the BSP thread type fittings seal using metal to metal angled surfaces or a combination of metal to metal and an O-ring. The angle of the sealing surfaces is 60° for both forms.

What does JIS fitting stand for?

Japanese Industrial Standards (JIS) Threads JIS Threads. JIS. Japanese Industrial Standards. There are four popular couplings styles in Japan.

What is a JIS hydraulic fitting?

JIS fittings are typically used as hose adapters on equipment designed and/or manufactured in Japan and Korea. Parker's JIS adapters are designed with 30° flare and 60° cone connections and typically incorporate BSP threads.

Are SAE and JIC fittings interchangeable?

SAE and AN/JIC fittings are completely incompatible due to the different flare angle. Furthermore, AN fittings (or those complying with subsequent standards) and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.

How do I know what size hydraulic fitting?

You would first measure the OD of the male. Or idea of the female. Once you have established the

What is the most common An fitting?

The most common uses of AN hoses on race cars:

-3 AN fittings used for brake lines.
-4 AN fuel hoses.
-6 AN fuel or coolant hoses.
-8 AN a very common size for coolant and oil.
-10, -12 AN fittings are used on either coolant or vent hoses.

Where are hydraulic fittings used?

Hydraulic fittings are components used in hydraulic systems to connect hoses, pipes, and tubes. In general, hydraulic equipment works under high pressure and is often not a fixed system.

Is JIC 37 or 45?

The JIC female has straight threads and a 37° flare seat. The Seal is made on the 37° flare seat. The SAE 45° flare male will mate with an SAE 45° flare female only. The SAE male has straight threads and a 45° flare seat.

Why is it called JIC fitting?

What does JIC stand for? JIC stands for the Joint Industries Council, which first standardized industrial use fittings. These compression couplings have a 37° flared seat on the male and female threaded connections.
